Deprecated funcion civicrm_contribution_recur.trxn_id for Recurring Contribution
When creating a recurring contribution from a contribution page, after successfully creating the contribution in Civi and Stripe, the user sees the following error on the thank-you (receipt) page:
User deprecated function: Deprecated function civicrm_contribution_recur.trxn_id, use civicrm_contribution_recur.processor_id. in CRM_Core_Error::deprecatedFunctionWarning() (line 1044 of /var/www/xxx/sites/all/modules/civicrm/CRM/Core/Error.php).
I can't tell where that is coming from or how to debug it. It seems like the contribution gets created correctly, from what I can tell.
